add license black list & white list detect function in LicenseCompareHelper

[XenoAmess]

add 2 functions to LicenseCompareHelper

There is a possibility that one of the children licenses in a ConjunctiveLicenseSet is also a ConjunctiveLicenseSet. To cover this case, you'll need to recursively descend the entire tree of licenses.

There is a similar, but rarer corner case for DisjunctiveLicenseSets where the children all contain white or black list items.

Once other request - could this be implemented without the additional dependency? I'm trying to keep the dependencies to a minimum.

@goneall

I think it is actually recursively now...

Can you provide some failing test cases? Thanks!

done.

Yes - you are correct. Sorry I missed that on my first review of the code.

Thanks @XenoAmess - Nice addition to the library!
